osama dead body conspiracy

There are news coming up that osama bin laden dead body is disposed of at sea in Islamic tradition.

what was there so hurry to perform this death ceremony rather than show to the world his dead body so that every one would believe he is really dead.

Why did they buried him so suddenly, now the conspiracy theories are saying all this Osama killing is hoax that US govt is saying.
we got to wait and see the real news as to whether US military still posses the Osama bin laden dead body or this news about disposing off his body at sea is some rumors.
